SAP2000 TUTORIAL ARCHES

SAP2000 TUTORIAL t ARCHES

The first step in the process of modeling an arch is to determine the Radius (R) and the angle

theta (θ) using the following equations:

L2

+ 4h2

R =

8h

L / 2

θ = sin -1

R

L

θ

h

The arch that will be modeled in the tutorial is shown below: it has a height (h) of 8 ft., sits on

columns that are twelve feet high and the distance between them (L) is 40 ft.

Calculating the radius (R) gives a value of 29 ft. and the angle theta (θ) is 43.6°.
